2 CONTEG SOLUTIONS for the next decade! TARGETED COOLING COOLING It stands to reason that the cooling of a facility does not need to be uniform as a concentration of blade servers will produce a far greater heat load than more traditional form factor servers or Storage Area Arrays and we don t often see a computer room featuring only one type of equipment. CONTEG Targeted Cooling gives the facility planner the flexibility to design different power zones within the data-center eliminating the need for a blanket approach which could lead to over-cooling of the facility in low density areas and high operational costs associated with too much cooling. CONTEG Targeted Cooling Solutions are available in four main types: Side Mount (see page 76), Rear Mount (see page 79), Top Mount and Wall Mount (see page 80, 81). The name represents the side of rack used for connection with the A/C or cooling unit. Rear and Side Mount solutions are designed to address the very high density heat loads typically found in today s data center or equipment room. Rear Mount solution represents a unique additional cooling system, while the side mount solutions can be applied as the main cooling system in various types of data centers. Open and Closed air loop architectures give a high degree of design flexibility to ensure that the cooling needs of the equipment can be met, whatever the design criteria may be. The highly efficient cooling units are available with capacities up to 36kW in a 300mm wide footprint to ensure that even the most demanding computing equipment environment can be kept at the optimum temperature. Chilled Water system uses chilled water to absorb heat from the air and sends it via a piping system to a chiller. A chiller transfers the waste heat to the atmosphere and is normally located outside. The required equipment includes chillers, cooling tower (or dry cooler), pumps and electrical control equipment. In Direct Expansion system, the evaporator is in direct contact with the air. The hot air from the IT equipment is directed over an indoor finned coil which transfers the heat to the liquid refrigerant. The heat is rejected in an other heat exchanger or outdoor condenser. The term direct refers to the position of the evaporator with respect to the air loop. The term expansion refers to the method used to transform the refrigerant (R410A) in the finning coil. Top and Wall Mount solutions have been developed for deployment in areas where there is insufficient cooling available to properly serve the needs of the equipment, for example in Telecommunications Closets or where insufficient capacity exists within the central air-conditioning system to cope with the heat load generated by extra equipment. :: targeted cooling TARGETED COOLING UNITS COMPATIBILITY The principles of installation and operation of all offered cooling systems are different. Due to this we have prepared an easy-to-read table with the compatibility information between chosen rack series and the Targeted Cooling systems. PREMIUM RACK SERIES PREMIUM rack series is the most suitable one to be used together with the complete range of Targeted Cooling solutions. All below presented PREMIUM rack series (RDF, RHF, RSF) are fully compatible with all solutions except rear mount cooling units in closed architecture, where only RDF racks are recommended to be used. Please note, that only 800mm wide racks can be used for rear mount cooling solutions. OPTIMAL RACK SERIES The ROF rack series is traditional, through years of proven rack series, which has been redesigned to maximize the compatibility with all data center solutions including Targeted Cooling products. Thanks to this, the ROF racks can be used in various projects using side open architecture cooling systems and can also be used together with rear mount cooling units in closed architecture and with wall mount A/C units.

3 SIDE SIDE MOUNT MOUNT COOLING COOLING UNITS UNITS CONTEG Side Mount Targeted Cooling is available in both closed and open air loop configurations. The Open Architecture units can be deployed in the cabinet row to deliver cooling directly to the cold aisle. Closed Architecture units provide the ultimate in available cooling with capacities up to 36kW. OPEN AIR LOOP ARCHITECTURE is ideally suited for use in hot/cold and contained cold aisle deployments and can be used to supplement the existing cooling system within a facility to add capacity on a zone by zone basis. Warm air is sucked directly from the hot aisle, cooled and humidified by the side mounted cooling units before being delivered back into the cold aisle for use by the equipment. The range of available capacities means that it is now easy to meet zone cooling requirements in a hot/cold aisle deployment without over-cooling the entire facility. Furthermore, side cooling can be combined with the CONTEG contained cold or hot aisle solution to further promote efficient use of chilled air leading to reduced facility operational costs. CLOSED AIR LOOP ARCHITECTURE is ideally suited for very high heat density racks where traditionally delivered cooling air may not provide sufficient capacity for the very high thermal loads generated by equipment placed in the racks. Additionally, the side mount closed architecture ensures that heat generated within the cabinet is removed at the point of production and not released into the data center environment, thereby minimizing the chances of localized hot-spots forming in the high density zones.

6 CONTEG SOLUTIONS for the next decade! REAR REAR MOUNT MOUNT COOLING COOLING UNITS UNITS The rear mount cooling units are designed for cooling of very high thermal loads that are typical for modern data centers and server rooms. The range includes cooling units with cooling output up to 18 kw. The cooling units architecture offers two versions - a closed air circuit and an open air circuit. Top view - air flow detail - open air-loop architecture Top view - air flow detail - closed air-loop architecture :: rear mount cooling units Architecture with an open air circuit The rear mount cooling unit with open circuit is suitable for application in data centres with traditional arrangement, i.e. with identical orientation of all racks in a data center. After passing through a rack, the air is cooled and it passes to another corridor where it is sucked by the next rack row. Architecture with a closed air circuit The rear mount cooling units with a closed circuit are ideal for cooling of hot spots - extremely hot local points in the rack vicinity. Therefore, they can be used not only in newly established data centers, but in older centers as well, where increased output of the equipment installed results in a problem concerning sufficient cooling of hot spots.

7 TOP TOP MOUNT MOUNT A/C UNITS A/C UNITS CONTEG Top Mount solutions deliver exceptional cooling capacity without adding to the floor-area required for the rack. The Top Mount cooling solution is available in capacities ranging from 900 Watts to 6000 Watts (approx BTU/Hr) to give the correct required cooling without over-cooling. These cooling units are compatible with the free standing racks, series RHF, RDF, RSF. The Top Mount solution is a stand-alone direct expansion (DX) solution which means that no additional plumbing or piping is required. Condensate is eliminated thanks to a Condensate Dissipater (1.4 kw version and above) and triple condensate protection system. This means that the condensate normally associated with air-conditioning systems is eliminated, giving total flexibility for deployment. The Top Mount solutions all feature electronic control boards as standard which give superior control of the air conditioner over standard electromechanical types. The Electronic Control Board ensures that the Top Mount units are running at optimal efficiency and not overcooling the cabinet. When installing these units into closed areas always make sure that the room has sufficient clearance and adequate ventilation so that environmental operating conditions (up to 55 C) are not exceeded. DESCRIPTION Cooling output of cooling units kw Compact design - coolant piping distribution systems are not necessary Condensate evaporation system (standard on units of 1.4 kw and above) eliminates the need for condensate drainage The triple protection system ensures condensate cannot enter rack The heat exchanger surface has been treated specially to provide the highest possible resistance against clogging, therefore the unit is able to operate with full output even when the ambient temperature reaches 55 C The cooling system was designed for operation without filters reducing ongoing maintenance requirements The cooling units have easy to use electronic control boards for accurate and easy setting of the required temperature in the rack Air flow through the rack - top mount cooling In the case of a high temperature within the cabinet, alarm contacts will operate. This means that the Top Mount solution can be tied into existing monitoring systems or CONTEG s Rack & Environment Monitoring System to alert remotely if the temperature exceeds user defined thresholds. :: top mount A/C units TOP MOUNT A/C UNITS ¹ Required Cooling and Part Numbers (Includes Top Mounting Collar) Compatible Rack Full Part No. 0.9 kw 1.4 kw 2 kw 2.8 kw 4.1 kw 6 kw RSF-42-60/80T-GWSWA-ACA-B AC-TM-09-60/80 AC-TM-14-60/80 AC-TM-20-60/80 AC-TM-28-60/80 AC-TM-41-60/80 RSF-42-60/10T-GWSWA-ACA-B AC-TM-28-60/100 AC-TM-41-60/100 AC-TM-60-60/100 RSF-42-60/12T-GWSWA-ACA-B AC-TM-28-60/120 AC-TM-41-60/120 AC-TM-60-60/120 RSF-42-80/80U-GWSWA-ACA-B 2 AC-TM-09-80/80 AC-TM-14-80/80 AC-TM-20-80/80 AC-TM-28-80/80 AC-TM-41-80/80 RSF-42-80/10U-GWSWA-ACA-B 2 AC-TM-28-80/100 AC-TM-41-80/100 AC-TM-60-80/100 RSF-42-80/12U-GWSWA-ACA-B 2 AC-TM-28-80/120 AC-TM-41-80/120 AC-TM-60-80/120 RHF-42-60/10L-GWSWA-ACF-B AC-TM-28-60/100 AC-TM-41-60/100 AC-TM-60-60/100 RHF-42-80/10P-GWSWA-ACF-B AC-TM-28-80/100 AC-TM-41-80/100 AC-TM-60-80/100 1 Part numbers presented in configuration with standard extrusions, other types also available; racks in ligh gray (RAL 7035), for black (RAL 9005) write H instead of B in the end of rack's code ² For RDF racks simply write RDF instead of RSF in the rack's code; please note, that RDF load rating is limited to 500kg 80...to complete your network

8 CONTEG SOLUTIONS for the next decade! WALL WALL MOUNT MOUNT A/C UNITS A/C UNITS The wall-mount A/C units are installed instead of one of the rack side panels. Since it is mounted instead of the rack side panel, there is no limitation by the overhead clearance. These cooling units are compatible with the free standing racks, series RHF, RDF, RSF, ROF and RMF. The Wall Mount units are ideally suited to spaces where insufficient clearance exists to install a roof mount solution. CONTEG wall mount solutions are available with capacities ranging from 1.1 to 3.0 kw per cooling unit. Up to two CONTEG Wall Mount cooling units can be fitted to a rack with control of the units via an optional control box for redundancy with duty cycle balancing. When installing these units into closed areas always make sure that the room has sufficient clearances and adequate ventilation so that environmental operating conditions (up to 55 C) are not exceeded. DESCRIPTION Cooling output of cooling units kw Compact design - coolant piping distribution systems are not necessary Condensate evaporation system (available in output units of 1.4 kw and more) eliminates the need of condensate drainage The heat exchanger surface was treated specially to provide the highest possible resistance against clogging, therefore the unit is able to operate with full output even when the ambient temperature reaches 55 C The cooling system was designed for operation without filters - reducing maintenance costs The cooling unit has simple control as well as easy setting of the required temperature in the rack The electronic control panel ensures accurate control of the cooling unit in order to achieve the required climate inside the rack This cooling type can be installed easily even into already installed ROF racks (retrofit installation possible) - the side panel will be replaced by air-conditioning at installation; blanking panels will be installed, too. It is necessary to fulfil the condition of IP rating 54. Air flow through the rack - wall mount cooling :: wall mount A/C units Wall Mount air-conditioning units retain the same cooling technology (Direct Expansion) as the Top Mount solutions.
